Abstract

There is provided an assembly for handling, transporting storing hydrogen, wherein the assembly comprises a component comprising a polymeric material (A) having a repeat unit of formula (I): —O—Ph—O—Ph—CO—Ph—(I) wherein Ph represents a phenylene moiety, and wherein the polymeric material (A) has a melt viscosity of at least 0.38 kNsm −2 . Also provided are a use of the polymeric material (A) in a component of an assembly for handling, transporting or storing hydrogen and a method of handling, transporting or storing hydrogen.

Claims

exact text as granted — not AI-modified

1 . An assembly for handling, transporting or storing hydrogen, wherein the assembly comprises a component comprising a polymeric material (A) having a repeat unit of formula I:

wherein Ph represents a phenylene moiety, and
wherein the polymeric material (A) has a melt viscosity of at least 0.38 kNsm −2 .

2 . The assembly of claim 1 ,
wherein the polymeric material (A) has an elongation at break, measured at −269° C., of at least 1.0%.

3 . The assembly of claim 1 ,
wherein the polymeric material (A) has a tensile modulus, measured at −269° C., of less than 5.8 GPa.

4 . The assembly of claim 1 , wherein the assembly is subjected to a temperature of less than −200° C. in use.

5 . The assembly of claim 1 , wherein the component is selected from the group comprising a seal, a valve, a part of a valve, a gasket, a bearing, a part of a bearing, a housing, a ring, an impeller, a storage vessel, a part of a storage vessel, a pipe, a part of a pipe, a pipe liner, a connector, insulation, for example for wire or cable, a bush, an umbilical, and a part of an umbilical.

6 . The assembly of claim 5 , wherein the component is a piston ring, a piston rod ring, or an impeller.

7 . The assembly of claim 5 , wherein the component is an umbilical or a part of an umbilical.

8 . The assembly of claim 1 , wherein the component comprises a sensor and/or a transducer.

9 . The assembly of claim 1 , wherein the polymeric material (A) is a homopolymer.

10 . The assembly of claim 1 , wherein the component further comprises a composite material and/or a metal.

11 . The assembly of claim 10 , wherein the polymeric material (A) is bonded to the composite material and/or the metal.

12 . The assembly of claim 10 , wherein the component is a pipe or storage vessel comprising a layer comprising the polymeric material (A) and a layer comprising the composite material and/or the metal.

13 . The assembly of claim 12 , wherein the pipe or storage vessel comprises an inner layer comprising the polymeric material (A) and an outer layer comprising the composite material and/or the metal.

14 . The assembly of claim 12 , wherein the pipe or storage vessel comprises an outer layer comprising the polymeric material (A) and an inner layer comprising the composite material and/or the metal.

15 . The assembly of claim 12 , wherein the pipe or storage vessel comprises at least two layers comprising the polymeric material (A) and at least one layer comprising the composite material and/or the metal.

16 . The assembly of claim 1 , wherein the component further comprises a polymeric material (C) having a repeat unit of formula I:

wherein Ph represents a phenylene moiety and a repeat unit of formula III:

wherein Ph represents a phenylene moiety.

17 . The assembly of claim 16 , wherein the component comprises a metal and the polymeric material (C) is bonded to the metal and to the polymeric material (A).

18 .- 21 . (canceled)

22 . A method of handling, transporting or storing hydrogen, the method comprising:
